This game was played yesterday, Feb 21st in a top level World Championship match. If we strictly count the points on both sides, material is equal because white has 2 Knights for a Rook and a pawn; also both Kings look exposed. Your tasks:
a) Analyse the position and decide who stands better and why
b) Black to move and win the game

Total available points for this puzzle is 20. The answers will be published next time together with puzzle #311.

Puzzle #309 solution:
Game Ivanchuk – Aronian. Coco's answers were:
a) We are near the imaginary border between middlegame and endgame because:
1. The queens on both sides are off the board
2. Both kings are out and active (to support the pawn promotion)
3. Both sides can exchange pieces right now, hereby simplifying the position, and multiple pieces have traded off already
4. The pawns are starting to advance in hopes of queening

b) White has the advantage over black because:
1. White has doubled rooks in the semi-open file in the center, and is in more aggressive stance in comparison to black. (rooks and bishop pointing directly and indirectly at the king in the center of the board)
2. Black's king is in the center
3. It is white's turn to move
4. Black has the IQP in the near-endgame

c) The best line:
