Re: interesting position

IMHO, the scores are too much close to make a good test position : Stockfish_18110421_x64_modern: 44/74 05:09 3 076 271 679 9 946 204 +2,52 17.Nxc7+ Kf7 18.Qg4 g5 19.Qe6+ Kg7 20.Qf5 Kg8 21.d6 gxf4 22.d7 Rxc7 23.Rxc7 Qxc7 24.Qd5+ e6 25.d8Q Qxd8 26.Qxd8 Kf7 27.Qd1 Be7 28.Qxa1 Rc8 29.Qd1 Rc5 30.a3 Rd5...

To analysis.sesse.net owner : disable contempt

Last game I followed on analysis.sesse.net, I saw that when it's white to play score is higher for white and it's black to play score is higher for black.

Re: The Petroff Defense 4. Nd3

The real peril started on white's 67th move and ended on black's 68th move. Carlsen put himself in a forced checkmate position, and four plies later, Caruna let him off the hook: ...

Re: 62 test positions from last couple of months

The really difficult problem from this set of 62 is this one: Nq3n1k/8/P1p2Npp/2Kp3R/pp6/n3p3/8/4Q3 w - - acd 59; acs 620; bm Nc7; c0 "Rxh6+ is bad (leads to a draw) while Nc7 wins"; c3 "Nc7"; c6 ... Thanks to your message, I just see that Arena misinterpreted the EPD. "Rxh6?" was a remark but Aren...
