So we will try to look at some long games of Komodo 5 single 64 bits on Playchess.
On this server, like I guess many others, people are running mostly Houdini 2.0c on 6 cores computers. So we have to always keep in mind that theses games are played mostly for fun and to analyse Komodo playing style.

On this first game, Komodo 5 is playing White and is out of book after 10...h6 in a B90 Sicilian Najdorf with 6.Be3

[d]rn2kb1r/1pq2pp1/p2pbn1p/4p3/4P1P1/1NN1BP2/PPP4P/R2QKB1R w KQkq - 0 10

This variation is not much played and there are only two games on Playchess Livebook for 11.Qd2 and that's the move played by Komodo with evaluation of 0.23

[d]rn2kb1r/1pq2pp1/p2pbn1p/4p3/4P1P1/1NN1BP2/PPPQ3P/R3KB1R b KQkq - 0 10

Strangely by transposition, we know have 29 games on Playchess livebook for this position

Houdini is out of book after 12.a4*

[d]r3kb1r/2qn1pp1/p2pbn1p/1p2p3/P3P1PP/1NN1BP2/1PPQ4/R3KB1R b KQkq - 0 12

We can notice that Komodo 5 is trying to have some space, playing 11.h4 then 12.a4.

[d]r3k2r/1q1n1pb1/p2p2pp/P2Pp2P/1p3PP1/1N5B/1PPQ4/2KR3R b kq - 0 20
After 20.h5 we have Houdini still playing King in the middle and Komodo is still pushing his pawns up on king side.

After 20.Qg6+ White are now in a better position. Black King is almost forced to go to d8 and will remain in the middle. I don't like White bishop on h3 but h column can be activated quickly, same for f column. Komodo like this position and gives it a +1.17 but Critter 1.6 more like +0.89 and Houdini +0.91.

Few moves later, after 28...Nc5 we are in the following position :

[d]2rk3r/1q6/p2p3p/P1nPb1p1/1p4P1/1N3Q2/1PP5/1K1R1B1R w - - 0 29

Here the nice move 29.Rxh6! and I thought that this would have definitely open the position to a nice ending for Komodo.

[d]2rk3r/1q6/p2p3R/P1nPb1p1/1p4P1/1N3Q2/1PP5/1K1R1B2 b - - 0 29

But now look at how Houdini is doing something really great : In the same time Houdini weakened Komodo pawn structure and put his king in safety.

29....Rxh6 30.Qf8+ Kc7 31.Qxh6 Nxb3 32.cxb3 Kb8 33.Qxg5 Qc7!*

[d]1kr5/2q5/p2p4/P2Pb1Q1/1p4P1/1P6/1P6/1K1R1B2 w - - 0 34

Now Black is two pawns down but are threatening Qc2 and Qxa5 at the same time.
White has a g passed pawn but have weaknesses in his defense.

Opposite color bishop endings are also often drawn.

[d]1k6/2r5/3p2P1/p2Pb3/1p1q4/1P1B4/1P2Q3/1K3R2 b - - 0 47

After 47.g6 Komodo is pushing his passed pawn.

[d]1k6/2r3b1/3p2P1/p2P4/1p1q4/1P1B4/1P2Q3/1K3R2 w - - 0 48

Blocked by Houdini's bishop.

Then they decided to exchange queen and the endgame was drawn as expected.

[d]1R6/8/1k1K4/8/2B5/7r/8/8 b - - 0 88

Despite the CPU superiority, Houdini had always been under pressure. Komodo didn't succeed in pushing the advantage to a win.

Hello,

I guess just one or two position to mention for Larry and Don.

After 46.b5

[d]8/r3bpk1/2Rp2p1/1P2p1Pp/4B2P/1KP2P2/r7/3R4 b - - 0 46

Komodo played 46...Ra3+?!. Seems that 46...Ra5!? is better.

After 49.c4

[d]8/4bpk1/2Rp2p1/1P1Kp1Pp/r1P1B2P/5P2/1r6/3R4 b - - 0 49

Komodo played 49...Bf8??
