Variant baseline (fidelity)
- Croatian Ties is played on a 10x10 board and introduces one new piece: Pegasus.
- Light starts from the bottom and Dark from the top; lower-right corner is a light field.
- Classical Chess rules remain the baseline unless explicitly modified by this variant.
- Core terms in the book use step-fields, capture-fields, steps, and ply sequencing.
Pegasus, pawn rush, en passant, castling
Pegasus: starts with Knight-like initial jumps, then may continue in the chosen heading from nearest reachable step-field to furthest, without changing direction.
Blocking/capture behavior: own piece on a Pegasus step-field stops movement at the previous step-field; opponent piece on a step-field can be captured and ends the move there.
Rush and en passant: identical to Classical Chess logic, except initial pawn rush extends up to 3 fields in Croatian Ties, creating additional en passant opportunities.
Castling: classical constraints remain, but the King may move 2 or 3 fields; after castling, the Rook always ends immediately next to the King on the inside (toward center).
