Draw , or not ??

Post by Carbec »

Hi,
I can't get an idea about this position :
[d]4rrk1/p1p2p1p/1pbq1b2/4N2Q/3Pp3/8/PPP4P/R1B1K2R w KQ - 0 17
Even Stockfish doesn't be sure.
What do you think ?

Look's like a "race" rather than a "draw": white's king is horribly exposed given that the queens are on the board, but white has the more obvious checkmating threats.

It would be an unpleasant position for me, regardless of the side.
