Senpai 2.0

[tpoppins]

Senpai could really benefit from at least 5-men TB support. In a game from a recent 40/4 4CPU CCRL gauntlet it reached the following position against Fritz 16:

[d]8/8/k3b3/3p4/2pK4/8/8/3B4 w - - 0 159

This is a 6-men TB draw, and the only move to draw is 159.Kc5. Senpai played it and found several other only-moves until here

[d]8/5bk1/8/3p4/B1pK4/8/8/8 w - - 0 177

where after a 17-seconds think it blundered with 177.Bc6 (177.Ke5 was the only move) and F16, using 5-men Nalimov, naturally didn't let the win slip away.

[Guenther]

Senpai could really benefit from at least 5-men TB support. In a game from a recent 40/4 4CPU CCRL gauntlet it reached the following position against Fritz 16:

[d]8/8/k3b3/3p4/2pK4/8/8/3B4 w - - 0 159

This is a 6-men TB draw, and the only move to draw is 159.Kc5. Senpai played it and found several other only-moves until here

[d]8/5bk1/8/3p4/B1pK4/8/8/8 w - - 0 177

where after a 17-seconds think it blundered with 177.Bc6 (177.Ke5 was the only move) and F16, using 5-men Nalimov, naturally didn't let the win slip away.

I don't think 5men would have helped here. The evals tell otherwise.
If F16 used 5men here it was as clueless, which you can easily see from the pgn output. Before the 6men drawing move 177. Ke5! it still thought it was up +3.16... (conversion to 5men is far away)

It would be easy to test though by just setting up both with 5men from a position before move 177 and see what's the outcome with a lot of games
and color changes and compare with the outcome when the Black side has no tbs at all.

Moreover I don't think a lot of people test with 6men (not speaking of online contests or analysis of course).
