I suggest you to implement a SEE function and discard moves where SEE < 0
The one described in the wiki is pretty good. Rhetoric has this function adapted. You should see a speedup.
This see, am I supposed to do something like:
int see(someting)
{
doMove()
generateMoveList()
see()
undoMove()
}
Or is it enough to just check which of the opponent with the lowest eval can re-catch and so on (swap colors) until all of them are evaluated?
Because this step of generating a list of moves can be rather cpu-intensive.
Here is a very good explanation.

knigths move in "L" shape ¿right?

Does Nodes go up........what about all the nodes it bypasses because of the TT entry ? Does that men nodes go down ? But now its searching new nodes....so do nodes go up ?
Do you assume that nodes go down because of the TT and then they go up because of the extra search.....does this mean the node count is not as significant
It depends on how you terminate your search. If you do a fixed-depth search, e.g. depth 7, then of course correctly using a TT will lead to a lower overall node count than not using a TT. If you do a fixed-time search, e.g. 60 seconds, then using a TT will let you search deeper (and reduce the EBF) but the overall node count will not be affected much, assuming that NPS is roughly the same with TT or without TT. (In fact this is not quite true since processing a node with a TT hit is faster than for other nodes, but this will go mostly unnoticed unless TT is also used within quiescence search.)

Are "Qnodes" now included within "Nodes"?
Do you have an explanation why "Qnodes" is such a low number in your case? As I mentioned in a previous post, it should be about 80-90% of the total number of nodes.
Also your number of eval hash hits surprises me. The code that I saw (which might be old) already did the hash table lookup when encountering depth == 0, so it saved the whole Q-search results, not just the eval results. Is that somehow related to the low number of "Qnodes"?

Speed is about nodes per second. So you have to speed up move generation.
If you want to search deeper you have to skip more nodes.

That is way too many nodes.
Arasan's node count per ply (see last column), using this position
r1b1k2r/ppqn1ppp/2pbpn2/4N3/2BP4/2N5/PPP2PPP/R1BQR1K1 w kq -
1 0.00 Ng4 +0.62 119
1 0.01 Bf4 +0.76 170
1 0.01 Bf4 +0.76 409
2 0.01 Nxf7 +0.69 613
2 0.01 Nxf7 +0.69 2190
3 0.01 Nxd7 +0.79 3363
3 0.01 Nxd7 +0.79 4452
4 0.01 Nxf7! +0.98 4962
4 0.02 Nxf7 +1.04 5322
5 0.02 Nxf7 +0.92 6043
6 0.02 -- +0.74 7170
6 0.02 Bf4 +0.36 10264
6 0.02 Bf4 +0.36 10813
This is even using a wide window for the first few plies, so I can detect "easy moves." You should get be able to get much smaller numbers than you have (and if you do you will get to higher depths much faster).
I do all the forward pruning stuff that is standard now. But even if you just have null move you should be doing better I think. Static null pruning (
https://chessprogramming.wikispaces.com ... ty+Pruning ) is also very effective.

Both statements are not fully correct:
If move generation takes only a small portion of overall processing time (say, < 10%), which is the case in most serious engines, then speeding up move generation does not help a lot. In most cases choosing better algorithms will be the better choice.
Skipping more nodes is not the only way to achieve a deeper search, in many cases a better move ordering is the way to go.

I doubt if search can predict right move ordering efficiently. Skipping is what remains. And if all moves have about the same value move ordering is waste of time.

Sure, but it's safe to conclude that a hashtable is very important. You didn't specify (or I didn't read right) just turning off transpositions or hash completely along with best moves. But here's Nemeton with hash off completely.
Makes far less of a difference in depth for Nemeton than it used to. I think that has to do with late move style reductions/pruning. Without hashmoves as expected it actually prunes way more and less accurately.
Opening position. No PV without hash because I pull the PV out of the hashtable.
